IMPROVEMENT IN WINDOW-SASH SUPPORTERS.

Specification forming part of Letters Patent No. 38,372, dated May 5,1863.

.To all whom it may concern.-

Be it known that I, FRANCIS P. CATLIN, of Hudson,ySt. Groix county,State of Wisconsin, have invented certain new and useful Improvements inWindow-Sash Supporters; and I do hereby declare that the following is afull, clear, and exact description ot' the construction and operation ofthe same, reference being had to the annexed drawings, making a part ot'this specification, in which- Figure 1 shows the position of thesupporter when holding the sash up; Fig. 2, the position when the sashis going up, and Fig. 3 the position when the sash is going down.

In Fig. l, K W represent the supporter, which is formed of a singlepiece o1 Inetal having the part K rounded on the end next the sash, andthe part W made thicker and heavier, so as to act as a weight or balanceto K. A strip of rubber, R, or other elastic substance, is inserted inthe sash, as shown in Fig. 1, against which the sash presses. The sashbeing down, the supporter stands as shown in Fig. 3. Now, when the sashis raised, the part K, being held against the rubber by the weightedpart V, is turned so that it is embedded in the rubber K, as in Fig. l.This presses the sash against the opposite side of the window, and thefriction thus produced holds the sash in position. By pushing upwardagainst the sash again the supporter is thrown in the positionrepresented in Fig. 2. The heavy end W then holds the part K against therubber ready to be turned when the sash is lowered. The sash can thus beheld at any point desired. I

This supporter can be placed in a box, a b c d, and can be inserted inthe casing at any point where the sash can operate upon it, or may oeplaced'in the sash at any point desired, and the rubber placed in thecasing.

Instead of the strip of rubber being placed in the sash or casing, thepart K, as shown at VB, may be faced with the rubber S, or any otherelastic substance, and it can be operated in a similar manner.

I am aware that rubber is already used on periphery of Wheels oreccentrics for a similar purpose; but

What I do claim, and desire t0 Letters Patent, is-

l. The combination of the arm or lever K and the weight W, inserted inthe casing as described, with the rubber or other elastic substance Rinserted either in the. sash or in the lever K.

2. The lever K and weight W, inserted in the sash, with the rubber orother elastic substance attached to either the'casing or arm K,substantially as and for the purpose described.
